The differences between a medical subluxation and a chiropractic "vertebral subluxation" create confusion and difficulties when it comes to following official ICD-9 and ICD-10 coding. In a 2014 article in Dynamic Chiropractic [ 21 ] by a chiropractor who is a certified professional coder , these difficulties were discussed in detail.
The impact factor relates to a specific time period; it is possible to calculate it for any desired period. For example, the JCR also includes a five-year impact factor, which is calculated by dividing the number of citations to the journal in a given year by the number of articles published in that journal in the previous five years. [14] [15]
In any given year, the CiteScore of a journal is the number of citations, received in that year and in previous three years, for documents published in the journal during the total period (four years), divided by the total number of published documents (articles, reviews, conference papers, book chapters, and data papers) in the journal during the same four-year period: [3]
Anti-vaccinationism in chiropractic is widespread, [1] [2] but there are notable differences within the trade. [3] Chiropractic is a form of alternative medicine founded on the idea that all disease is caused by disruption of the flow of "innate" (or innate intelligence) in the spine, by so-called vertebral subluxations – a pseudoscientific concept.
According to the World Health Organization, a subluxation is a "significant structural displacement" and is therefore visible on static imaging studies, such as X-rays. [2] [3] [4] Unlike real subluxations, the pseudoscientific concept of a chiropractic "vertebral subluxation" may or may not be visible on x-rays.
The journal states that their aim is to assess solely the scientific validity of a submitted paper, rather than its perceived importance, significance, or impact. [2] In September 2016, the journal became the largest in the world by number of articles, overtaking PLOS ONE. [3] [4] [5]
The journal usually has the highest impact factor of the journals of internal medicine. According to the Journal Citation Reports, NEJM had a 2017 impact factor of 79.258, [37] ranking it first of 153 journals in the category "General & Internal Medicine". [38] It was the only journal in the category with an impact factor of more than 70.
The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. [1] Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals.
